Application filed November 14., 1887. Serial No. 255.050. (No model.)

are applied to the doors of houses to enable a person to partially open the door and see who is outside withoutreleasing the doorfastening so as to permit that person to enter. Such devices ordinarily consist of a chain having upon its end a headed stud or bolt Yand. a keeper containing a slot to receive the bolt, one of said parts being secured to the door and the other tothe jamb, or said parts, in the case of double doors, being secured one to each door. The chain is ordinarily attached to a chain-plate, whereby it is secured tothe' door, and which has upon it a hanger on which the bolt may be hung when it is-not desired to use it,fand which avoids the swinging of the bolt upon its chain and consequent marring of the door. In the ordinary chain-bolt a special manual operatiouis required to place the bolt upon its. hanger afterits withdrawal from theslot of the keeper, and this is very often neglected by 'servants and others, and the bolt is -left to swing by its chain. f

The object of myinvention is to so construct the parts that the bolt, when the door is closed, cannotbe withdrawn from the slot in its keeper without placing it in the hangeron the chainplate, where it will be retained by gravity,thus

dispensing with any special manual operation to place the bolt upon its hanger.

The invention consists in the combination, with a chain audits bolt, of a keeper having substantially parallel slots for the bolt which communicate with each other at their inner ends, and one of which is blind or closed at its outer end, while the outer end of the other is open, and the hanger or chain-plate, to which the chain may be secured, and which has in it a slotor pocket the mouth of `which is opposite the open-ended slot in the keeper and in which the bolt is held by gravity.

In the accompanying drawings, Figure l is a front elevation of my improved'device. Fig. 2 is a transverse section of the keeper and a portion of the door to which itis secured, taken on the plane of the dotted line ww, Fig. 1; and

of the. dotted line y y; Fig. l.

Similar letters of reference designate corresponding parts in the several` figures.

A B designate, respectively, the keeper and l the chain-plate, which are secured, respectively, one to the jamb orframeof the door and the other to the door, or in case of double doors they are secured one to each door.'

Eig. 3 is ahorizontai section uponthe piane y UNITED STATES-` PATENT OFFICE,

C'designates a chain of the ordinary kind,

which may be secured to the chain-plate B, as is shown at b, and which has at its end a bolt or headed stud,0, ofthe ordinary character. krlhe keeper A is constructed with two slots or channels, ,a a', with which thebolt or headed stud C' may be engaged andin which the bolt is free to slide. These channels a a communicate with each other at 4 their inner ends, as shown at a2,

and extend substantially parallel with each other in the keeper; One of the slots, a', at its l* f outer end is blind or closed, as shown at a3, while the outer end of the other slot, `on, is left `open, so that the bolt C maybe entered. there- As here represented, the blind sl'ota/isinto. below the open ended slot a," but it may be upon either side thereof. When the door is Y to be bolted, the bolt Cf is. raised from the` hanger b into the open end of the slot a,'the

door being then closed, and the bolt is passed tothe end of the slot a'A and dropped downward into the slota. The openingof the door will then produce a pull'upon the chain C and will draw thebolt C along theslot a to its blind end a3, whereuponany further openingof the Y door will be prevented. L

Wh en it is desired to open the door, thebolt C is slid along the Ablind slot a tothe inner end thereof, isk then raised upward into the slot a, and slid along said slot a toward the righthand of the drawings and out at the open'end thereof into engagement with the chain-plate Y B. In the chain-plate 4B is al hanger, which consists of an vangular slot, b', adapted to receive the head of the bolt, and the open end or ymouth of which is presented directly opposite the open end of the slot a. Consequently, as the bolt'is slid out` of the slot a it is unavoidably entered into the hanger or pocket b,"and,l

drops therein by gravity, Where it is held, as

Iook

representedin Fig. 1. When the door isclosed and it is desired to bolt it, the bolt C is raisedl by hand and slid from the hanger or pocket b vdirectly into and through the slot a until it reaches the inner end, a2, thereof, where it drops into the blind slot a.

From the above description it will be understood that inasmuch as Whenever the bolt is to be removed from the keeper, the door being closed, it must necessarily be entered into the hanger or pocket b',wherein it is held by gravity, and inasmuch as no additional manual operation is necessary to place the bolt in the hanger or pocket b', it will not be left hanging by the chain through carelessness and per'- mitted to swing to and fro and mar the door.

What I claim as my invention, and desire to secure by Letters Patent, is-

pocket b', the mouth of which is opposite the open-ended slot in the keeper, and in which the bolt is held by gravity, substantially as herein described.
